SPECIFICATION forming part of Letters Patent No. 757,501,1dated April 19, 1904.-.

Application iiled June 20, 1903,

To LZ what@v t incl/y concern.'

Be it known that I, GEORGE BCHER Rows, a citizen of the United States, residing at Moore, in the county of Cleveland and Territory of Oklahoma, have invented certain new and useful Improvements in Presses, of which the following is a specication.

This invention relates to presses of the rebounding type and which are practically continuous in operation, the density of the bale being regulated by frictional engagement thereof withthe sides of the balingchamber, said sides being adjustable to contract the outlet or discharge endY of the baling-chamber to a greater or less degree. The plunger or follower is of the rebounding variety and pivoted side wings cooperate therewith, said wings when moved inward forming, in effect, continuations of the sides of thebaling-chamber and when spread forming a compartment into which the loose material. is adapted to be thrown from a wagon by the ordinary hayfork, thereby obviating the use of a special feeder. The power which comprises a drum and sweep is adapted to have the drum reversed to vary the strokes of the plunger during a complete revolution of the drum. In one position of the drum the plunger has imparted thereto two strokes, and the drum when reversed imparts three complete strokes to the plunger during each revolution.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction ofthe means for effecting the result reference is to be hadV to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modiication, still the preferred embodiment of the invention is illustrated `in the accompanying` Fig. 3 is a top plan view of they Serial No. 162,398, (No model.)

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the saine reference characters.`

The press is adaptedy to occupy the Vmost convenient position, and in practice Aispreferably arranged horizontally upon a selected part of the ground and is staked or otherwise secured thereto, so as to resist the strain and shock incident to the peculiar character of work to be performed. The power for operating the .press may be of any type and is of the variety adapted to be operated by horse and is located at a proper distance from the press and is anchored or otherwise pinned to the ground, so as to resist the load. To increase the stability of the mechanism, braces 1 are interposed between the framework of the press and power, as shown most clearly in Fig. 1.

The press comprises a bed-piece 2, sides 3, and top 4. The bed-piece 2 supports the operating parts and constitutes the lower side of the baling-chamber. The parts 4 and 3 constitute, respectively., the top and sides of the baling-chamber. Pivoted catches 5 are locatedat the inner or receiving end of the baling-chamber, and their hooked ends are pressed inward by springs 6, located in pockets or housings at the outer sides of thevwalls 3. The hooked ends of the pivoted catches 5 normally extend into the baling-chamber, so as to engage with the charges when compressed and prevent the same following the movement of the plunger when returning to a normal position. The side walls 3 are strengthened by truss braces 7, as shown most clearly in Fig. 5. The side walls 3 oi' the baling-chamber are free at the inner or delivery end of the press, so as to move inward or outward, as may be required, to vary the transverse distance between the said walls 3 at the discharge end of the baling-chamber, whereby the density oi' the bales may be regulated. A frame encircles the inner end of the baling-chamber and comprises companion vertical bars 8 and cross-bars 9, the latter having their end portions longitudinally slotted to receive the bolts or fastenings 10, by means of which the several bars 8 and 9 are connected. The cross-bars 9 are prevented from vertical movement; but the vertical bars 8 are adapted Yto have a limited lateral movement to proouter ends of the tension-bars 11 and the ver-- tical bars 8. The upper tension-bar is stayed by braces 14, which are connected at their lower ends to a cross-timber 15, secured to the vbed-piece 2, and which are provided at their upper ends with eyes through which said tension-bar passes. These stays 14 also serve to brace the upper portion of the frame encircling the delivery end of the baling-chamber. A loop 16 is formed at one end ot' each of the tension-bars 11 and is adapted to receive a crank portion 17 of crank-shaft 18, 'journaled near its ends in bearings 19 at one end of the cross-bars 9. The crank-shaft 18 is provided intermediate of its ends with a crank 20 to facilitate turning of the crank-shaft in its bearings when it is required to move the tension-bars 11 longitudinally to admit of the sides 3 moving apart to a greater or less extent. A pin 21 is loose upon the crank portion20 of the crank-shaft and is adapted to be engaged with a side of the baling-chamber, so as to hold the crank-shaft 18 in the required position. When the crank-shaft 18 is turned in the bearings 19, the crank portion 17 coperates vwith the loops 16 and effects a longitudinal movement of the tension-bars 11, so as to vary the inward pressure of the tensionsprings 12 and 13 upon the sides 3 for the purpose stated.

Standards 22 are secured at their lower ends to the bed 2 at each side thereof, and wings 23 are pivoted at their upper edges thereto 'and at their lower edges to the bed 2. lThe pivot rods or axes of the wings 23 are indicated at 24, the same being near the outer ends of the wings. An arm 25 projects upward from the outer end of each of the wings 23, and a stout coil-spring 26 connects the upper ends of the arms 25 and normally tends to draw the outer ends of the wings together, whereby their inner ends are spread apart, as indicated most clearly in Figs. 3 and 5. The inner ends of the wings are provided with teeth 27 to operate in the spaces formed between guards28, which appear as grates and curve transversely on the arcs of circles having the axes of the respective wings 23 as centers, whereby the inner ends of the wings 23 maintain a close joint with the concave sides of the grated guards 28. By having the teeth 27 pass through the spaces formed between the bars or elements of the grated guards the material is prevented from wedging between the inner ends of the wings 23 I and said guards. A plate 29 is applied to the inner side of each wing 23 near its inner end and is pivoted to the wing at its inner edge and is free at its outer edge to move toward and from the plane of the wing. A spring 30 is interposed between the pivoted plate 29 and the wing 23 and normally presses the outer or free end of the plate 29 inward. This construction provides, in effect, yielding portions at the inner or free ends of the wings 23, which are adapted to give when the wings are moving inward at their inner ends to compress the material simultaneously with the' advance of the plunger to force the same into the baling-chamber, thereby obviating injurious pressure and strain upon the wings and coperating parts. The teeth 27 preferably consist of strips let into kerfs or saw-cuts formed in the inner ends of the wings and secured therein in any manner. A guard 31 is applied to the upper edge of each wing 23, and its upper portion is outwardly deflected,

whereby said guards 31 are upwardly fiared to facilitate the entrance of the material into the receiving-chamber when supplying material to the press.

The grated guards 28 may be of any formation and, as shown, comprise inner and outer upright bars and transverse strips', the latter being secured at their ends in any substantial way to said upright bars. These grated guards 28 close the spaces formed between the sides of the baling -chamber and the inner ends of the wings 23 when the latter are spread, as shown most clearly in Fig. 5.

A pressure-roller 32 islocated at the receiving end of the heling-chamber about in line with the upper wall 4 and is journaled at its ends in pendent portions of a pivoted frame 33. This pressure-roller 32 is adapted to turn in one direction only-that is, with the plunger and charge when the same are entering the baling-chamber-and is prevented from rotation when the plunger is returning to a normal position. Aratchet and pawl 34 coperates with the pressure-roller 32 to admit of its turning in one 'direction and to' prevent its rotation in the opposite direction. The frame 33A is located on top of the heling-chamber at its inner or receiving end and is pivoted at 35 and held down upon the heling-chamber by a tension-spring'36, which is mounted upon rod 37 and confined thereon between set-nut 38 and cross-bar 39. The tension of the spring 36 may be varied by moving the set-nut 38 upon the threaded end of rod 37.l The lower portion of the pressure-roller 32 normally extends beyond the llower side of wall 4, and hence exerts a downwardpressure upon the charge as the same is being forced into the balingchamber, thereby compressing the same in a perpendicular direction.`

The plunger or follower is indicated at 40 and may be of any construction, and as illustrated itis composed of a series of strips secured together, so as to form an open structure for the salie of lightness. The plunger or follower is slidably mounted upon the bed 2, and Vin order to minimize the friction it is mounted upon truck-wheels 41. In order to hold the plunger to the bed and insure its movement rectilinearly, plates 42 are secured to the top side of the bed 2, and their inner longitudinal edge portions are bent to form guides for the outer end portions of transverse strips 43 and 44 to engage under. These strips 43 and 44 are secured to the bottom side of the plunger or follower in any -substantial manner. A roller 45 is journaled to the upper inner corner of the plunger. and is designed to prevent binding of the plunger inthe baling-chamber when compressing the bale. A ratchet and pawl 46 cooperates with the roller 45A to prevent movement thereof in one direction, but admits of it turning freely in the opposite direction. Upper and lower transverse bars 47 and 48 are secured to the upper and lower sides of the plunger or follower, and their end portions project beyond the sides of the follower and support vertical rollers 49, which embrace the outer sides of the wings 23. As the plunger or follower is moved forward the rollers 49 travel upon the outer sides ofthe wings 23 and move the same inward, thereby compressing ,the charge laterally and causing said wings to aline with the -sides 3 of the baling-chamber and form, in eifect,'continu ations. thereof. The cross-bars 47 and 48 may be connected to the plunger in any substantial way, and, as shown, a bolt 50 is passed through coincident openings in said cross-bars and the plunger, thereby admitting of separation of the parts when desired for any' purpose. The plunger or follower is returned to a normal position by mea-ns of spring 51, which is connected at one end to the plunger and has adjustable connection at its opposite end to the bed 2, wherebythe tension of the spring may be varied to cause the follower to return at a`greater or less speed. A shaft 52 is journaled trans- 'versely of the bed 2, and an arm 53 projects upward therefrom, the end of the spring 51 being connected thereto. By turning the sh aft 52 the tension of the spring 51 may b e varied. To effect turning of the shaft 52, it is provided upon its outer end with worm-gear 54 in mesh with worm-thread 55 of vertical shaft 56, the head of which is apertured to receive operating-bar 57. The movement of the plunger is controlled in a measure by a regulator, the same consisting of a shoe 58, Vertical rod 59, and tension-spring 60, the latter 'being mounted upon the upper end of the rod 59 and conlined between set-nut 61 and cross-piece 62. The spring exerts an upward pressure on the rod 59, thereby pressing the shoe 58 against the under side of the bed 2 with a friction depending upon the tension of the spring 60, so as to offer greater or less resistance to the return movement of the plunger under the action of the spring 5l.

The draft rope or cable 63 is connected at one end to the draft-slide 64 and has adjustable connection at its opposite end with the plunger, so as to allow for variation in the distance between the press and its operating power when setting up the same. For convenience a windlass 65 is applied to the outer end of the plunger, and one end of the draft rope or cable 63 is secured thereto and the loose end portion adapted to wind thereon. A ratchet and pawl 66 cooperates with the windlass to prevent unwinding of the rope 63 therefrom when the parts are properly adjusted. The draft rope -orV cable passes beneath the baling-chamber, thence upward through a slot in the bed 2 to the windlass 65. This slot also provides a passage for the lower end of the rod 59. Y l The horse-power comprises a frame and a drum, the frameconsisting of transverse sills 67 and longitudinal sills 68 and 69, the same IOO being rigidly connected at their meeting ends. Transverse braces 70 stiften the frame and secure the parts against any play or movement, and their end portions are threaded and passed through openings in the longitudinal sills 68. Tie-rods 71 connect the transverse sills 67 and also pass through openings in the legs of keepers 72, so as to hold them rmly in place. The drum 73 is rotatably mounted upon the frame and is grooved in its periphery and is held in place by four bars 74, slidably mounted in the keepers 72 and having their inner ends snugly fitted into the grooved edge of the drum. The inner ends of the bars 74 are notched to form seats 75, in which are itted rollers 76, so as to reduce the frictional contact of the inner ends of said bars with the drum to the smallest amount possible. The bars 74 are held in place and adjusted by means of clamp-bars 77, the end portions of which are longitudinally slotted, as shown at 78, to receive the threaded ends of tie-rods 79, which pass through apertured ears 80, projected outward from the keepers 72. By having the end portions of the clampbars 77 longitudinally slotted they may be readily disconnected from the tie-rods 79 by loosening clamp-nuts 81 to admit of the bars 74 being moved outward, so as to release the drum 73 to admit of its reversal or substitution by means of another drum. The tie-rods 79 enter the grooved edge of the drum 73 and supplement the action of the bars 74 in holding the drum in place. The drum may be of any substantial construction and as shown is composed of upper and lower heads and an intermediate plate. Straight slots or guides 82 are formed in the heads of the drum and terminate in circular enlargements 83. If the drum is designed to impart two complete movements to the plunger during each complete revolution, the slot 82 is diametrically arranged, as shown in Figs. 13 and 14. For imparting three complete strokes to the plunger or follower during a complete revolution of the drum the latter is provided with lthree slots 82, having a triangular arrangement, as shown most clearly in Figs. 11 and 17, the circular enlargements being at the angles formed by the juncture of the slots. In order that a drum may be adapted for a twofold purpose, one head or side is provided with a single slot and the other head or side with a plurality of slots.

The draft-slide 64 is provided at one end with a head 84 and viiat shank 85, the latter adapted to travel in the straight slot 82. The head 84 is slightly larger than the openings 83 at the extremities of the slot 82, so as to hold the draft-slide in place. The Hat shank 85 is of a length to admit of the draft-slide turning in either one of the openings 83, Whereby provision is had for reversing the slide at each end of the slot and at each half-revolution of the drum. A plate 86 is secured to the frame of the horse-power and is provided with upwardly-extended cams 87 and 88, which cooperate with the shank 85 ofthe draft-slide to hold the same in place when turning at each end ofthe slot or guide-82.

For connecting the'draft rope or cable 63 to the draft-slide 64 spaced lugs 89 are applied to the draft-slide or formed therewith, and a wedge-shaped space is formed between their opposing sides for cooperation witha wedge 90, which is inserted in afold or bight'of the rope or cable 63. This manner of connecting the draft-cableto the .draft-slide admits of ready adjustment and also prevents injury to the connection.

The -sweep 91 is connected to the drum in such a manner as to admit of its ready detachment when the drum is to be reversed or the power to be stored. A brace-rod 92 connects the outer end of the sweep `Withthe drum, and a stay 93 connects the parts 91 and 92 at a point intermediate of their ends, a clip 94 connecting the stay with the sweep and a toothed dog 95 connecting said stayv with the brace-rod 92. A seat 96 is applied to the sweep for convenience of the driver.

The press and its operating power being arranged substantially as set forth and the sweep being rotated in the accustomed manner, the plunger or follower is alternately advanced and retracted. The return of the plunger is brought about by means of the spring 51, and its advance is accomplished by means of the eccentric movement of the-draft-slide with the drum when the latter is rotated.. When the slot 82 of the drum alines withV the direction of strain upon the draft rope or cable 63, the draft-slide assumes a position with its flat shank 85 in line with the slot or guide 82, thereby permitting the slide to move from the side of the drum remote from the press to the side or edge portion nearest the press. At this time the'plunger or follower is returned to a normal position by the spring 51. To prevent a too quick movement of the plunger and draftslide, the check or regulator comprising the following parts has been devised: Ablock 97 is located adjacent to the frame of the power and is provided-with a pulley 98, having its lower portion of conical form. This pulley 98 is mounted between plates 99 and 100, secured to the block 97. A pin or bolt 101 passes through openings of the block 97 and plates 99 and 1,00, andthe pulley 98 is mounted thereon. Clampbolt 102 is let into the block 97 and is provided with tension-spring 103, which exerts a downward pressure upon the plate 99. By turning the set-nut 104 the tension of spring 103 may be regulated, thereby causing the pulley 98 to be clampedfbetween plates 99 and 100 with a greater or less pressure. At or about the instant the plunger reaches the limit of its forward movement into the balingchamberthe draft rope or cable strikes the inclined portion of the pulley 98 and is caused IOO IOS

to pass between said pulley and the plate 100, whereby the draft rope or cable is subjected to tension which modifies the return stroke of the draft-slide and plunger, the latter being further controlled by means of the shoe 'in When the plunger is in ay the manner stated. normal position and the inner ends of the wings 23 spread, the space formed between said wings, plunger, and guards 28 constitutes a chamber into which the material to be baled is supplied by being thrown therein from the wagon. When the plunger is moved forward, the wings 23 are simultaneously moved inward, thereby compressing the material laterally and longitudinally. The several bales may be separated by spacing-blocks in the usual way, the operation of the press being practically continuous, as will be readily comprehended.

.To facilitate the turning of the draft-slide at the ends of the slots, a roller 105 is arranged at the end of the shank 85 facing the press, so as to sustain the strain.
